This is a question for my neighbor, He is looking to get a new small to mid-size tractor and he is looking at the kubota. The dealer told him that he could mow 3 times as much with the diesel engine(2 cyl.) than he could with the gas engine. I find this hard to believe myself but ya never know. So what are your opinion's on this?? I am not sure of what model, but he said it was going to be 4wd and I think 18 to 22 HP. Any info would be appreciated.
